The verify experiment proves that its ratio and phase characteristics are much better than ordinary ones and the precision is enough for measure use. zero - flux current transformer can ’ t obtain absolute zero flux because residuary flux, so when the secondary turns is too small it will not satisfying. to improve the precision further, proposes a method to compensate zero - flux current transformer using capacitance parallel connected coil and deduces it
為了進一步抵消剩餘磁通，提高互感器的精度，提出了一種並聯電容線圈補償零磁通的方法，並進行了理論推導，設計了基於該方法的100匝電流互感器，通過校驗證明它可以改善零磁通電流互感器的比差和角差特性，提高互感器的精度，將電流互感器的二次匝數由普通互感器的幾千匝降到了100匝，提高了測量微小電流的能力。 -

Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio. the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong, and distribution is wide. meanwhile, go rdonia acuminata, castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm, their distribution is limited. especially, the ju venile of pinus massoniana specialized outstandingly. with the devlopment of pinu s massoniana, which is the pioneer population in mt. jinyun, the environment become s unfit to it ' s juvenile. it turns to needle and evergreen broad - leaves mixed fo r est. because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis, gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators. the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession. the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession
對縉雲山森林植被的4個優勢種群3個年齡級生態位寬度進行了研究.結果表明，川灰木利用資源的能力最強、分佈廣，為典型的泛化種.大頭茶、栲樹、馬尾松對資源的利用在一定程度上特化，分佈上有一定的局限性.馬尾松的中齡組與幼齡組特化現象十分顯著.縉雲山森林植被的先鋒種馬尾松的發展，導致環境的改變不適于其幼齡個體的生長，群落演替到針闊葉混交林階段，最後發展為以栲樹等為建群種的常綠闊葉林.種群的資源利用能力，是種群分佈與群落演替的內在原因，光因子和營養元素（如n ）是群落演替的主要外部動力 -
A step - down transformer has a turns ratio less than 1
降壓變壓器的匝數比小於1 。 -
However, the refractive index will increase with the increase of the flow ratio of sifu / nhs, slightly increase with the increase of substrate temperate, and decrease with the increase of rf power. by measuring the passivation results of hydrogen plasma and sinx thin film, we found an evident improvement of minor carrier lifetime in polycrystalline silicon after hydrogen plasma treatment, although it has little to do with the annealing temperature and time. the hydrogen contained in sinx thin film can enhance the carrier mobility of monocrystalline silicon, but after annealing at high temperature the mobility turns down
通過測試氫等離子體鈍化和氮化硅薄膜鈍化的效果，實驗還發現氫等離子體處理對多晶硅材料的少子壽命提高作用比較明顯，但是這種提高作用與處理溫度以浙江大學碩士學位論文王曉泉2003年5月及時間的關系不大；氨化硅薄膜中的氫對單晶硅的載流子遷移率提高有一定作用，但經過高溫處理后這種作用消失；氮化硅薄膜能提高單晶硅和多晶硅的少子壽命，具有表面鈍化和體鈍化的雙重作用；氫等離子體和氮化硅薄膜都能有效地提高單晶和多晶電池的短路電流密度，進而使電池效率有不同程度（絕對轉換效率0 -
